Gublin & Green, as Armisen tells us, specializes "in assisting clients who have sustained injuries while working at, or attending, the Broadway musical, 'Spider-Man: Turn Off the Dark'! If you or a loved one have been affected by this show, do not waste a moment!!"

The kicker is that what Gubin & Green's clients win in return are (semi-spoiler)...more tickets to "Spider-Man."

Perhaps the best touch: The graphic of Frank Gublin as webslinging champion of theatrical justice. (The ad even advertises a real website address: gublingreen.com -- which takes you, naturally, to the website of..."Saturday Night Live.")

The sketch comes the same day as the Spider-Man musical had two safety violations issued against it by the N.Y. state Department of Labor, reported the New York Times. The finding reportedly also calls for surprise inspections of the production.

"Spider-Man: Turn Off the Dark" is the most expensive production in Broadway history -- at $65-million and counting. Last year, it began to come under fire after several performers were injured.

One of the high-flying Spider-Man actors, the physically rehabbing Christopher Tierney, fell from a 30-foot platform, reportedly sustaining four broken ribs, three fractured vertebrae, a broken shoulder blade and a hairline skull fracture.

It was in early December that Weekend Update anchor Seth Meyers (who once co-write a Spider-Man issue for Marvel) and Samberg the Spidey understudy first spoofed the musical's safety record.
